Cropping Homepage Features
Sometimes you may upload an image that doesn't quite fit your homepage feature space and black filler bars will show up on the sides of the image. By cropping the image you can manipulate the size to fit the exact dimensions of the space.
Tools > Homepage Features > Main Feature Tab OR Secondary Feature Tab
Step 1: Click on the pencil next to the feature you would like to crop.
Step 2: Select the Crop Image button
Step 3: Make sure the "Lock Aspect Ratio" box is checked (this will keep the crop the right size for your specific homepage).
